ASTM D2765 – 16

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applica- 1 These test methods are under the jurisdiction of ASTM Committee D20 on Plastics and are the direct responsibility of Subcommittee D They have been particularly useful for electrical insulations since specimens may be selected from those portions of the insulation most susceptible to insufficient crosslinking.

If the system is un? Such extraction test methods are described herein. A superscript epsilon e indicates an editorial change since the last revision or reapproval. Hence, determination of the gel content provides a means of both controlling the process and rating the quality of finished products.


If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. For Size 2 AWG and smaller, the dimensions should be proportionately less.

The surface-to-volume ratio shall be kept as small as reasonably possible. E—Ground-glass or cork joint. The inch-pound units in brackets are for information only.

Link to Active This link will always route to the current Active version of the standard. NOTE 7—The solvent must cover the swollen test specimen at the conclusion of the immersion period to obtain reliable results. Precision and Bias 7 NOTE 6—If the aetm of? Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Do not inhale the vapors. A small wire, attached to the cage and extending through the re? The inch-pound units aastm parentheses are for information only. Tests shall be discarded and repeated with a fresh test specimen if specimens are not covered with solvent at the conclusion of the extraction step.

It is not equivalent to ISO in any other measurement or section. The test strip used for extraction should be taken next to the conductor only when strand shielding tapes or compounds are not employed.


Fold over the open side of the pouch and staple the edge to form a cage. Note 1-ISO is similar to this test, but is not equivalent.

Blow the surfaces Note The methods described herein are applicable to crosslinked ethylene plastics of all densities, including those containing fillers, and all provide corrections for the inert fillers present in some of those compounds. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

Each laboratory obtained three test results for each material. C—Area most susceptible to insufficient crosslinking.

The principles of Specific precautionary statements are given in Sections 6, 10, and Provided that no chemical degradation occurs, the greater the degree of crosslinking the lower the amount of extract lower percent extract.

Reagents and Materials The test specimen should not be squeezed with the forceps.
